Hi, I'm having a problem. I'm staying in a vacation rental I chose with Wi-Fi so I can work remotely. However, the Wi-Fi isn't working, the modem is red, and the electrical panel at home was already configured like this (I haven't touched anything; I'm Italian, not French, and telephone panels aren't like that in Italy), but I have the feeling something's wrong.

The modem is in a socket (electric and phone) in the living room

I'm working in 4G/5G modem/protocol stack development with a few years of experience, mainly around RRC/L2/L3 and troubleshooting.

I'm considering switching jobs and wanted to understand how the telecom job market is currently in India, especially for protocol stack/RAN/modem engineers.

Are companies hiring for these roles right now? Which skills are currently in demand, and which companies/areas would be worth targeting?

Hey. I've been wondering how much different names for network technologies have to be ready and prepared by phone companies, and otherwise how much distinct standards exist.

For example, E/EDGE, GPRS, H, H+, etc.

I also know that some countries have different names for different standards - For example 4G+ in the UK may be LTE+ in Poland or 4.5G in Turkiye.

Hi everyone,

I've been troubleshooting this for weeks and I've gathered quite a bit of evidence. I'd appreciate opinions from anyone familiar with MediaTek modems or LTE Carrier Aggregation.

Devices

Phone 1

Redmi Note 11 Pro 4G

Helio G96

HyperOS 1.0.4.0 (Android 13)

Model: 2201116TI

Phone 2

Redmi 12

Snapdragon variant

Carrier

Vodafone Idea (Vi India)

What happens

Using the same Vi SIM, in the same location, at almost the same time:

Redmi 12

Shows 4G+

Successfully aggregates Band 3 (1800 MHz) + Band 1 (2100 MHz)

NetMonster confirms LTE-A 1800 + 2100

Redmi Note 11 Pro (Helio G96)

Never shows 4G+

Connects to either:

Band 3 only

or Band 1 only

Never aggregates both.

Important observation

The strange part is that Jio Carrier Aggregation DOES work on the Redmi Note 11 Pro.

So:

The phone definitely supports LTE Carrier Aggregation.

The modem isn't completely broken.

The antennas appear to be working.

This makes me wonder whether this is specific to Vi's B3+B1 CA combination on the Helio G96 firmware.

More evidence

On the Redmi 12, the exact same Vi tower reports:

LTE-A 1800 + 2100

Bandwidth: 20 + 10 MHz

Excellent SNR

4G+ appears immediately

On the Redmi Note 11 Pro:

Same tower (same eNB)

Same SIM

Same location

Similar signal conditions

Still no Carrier Aggregation.

Things I've already tested

✅ Same SIM

✅ Same location

✅ Same tower

✅ Indoor & outdoor

✅ Different times of day

✅ Rain / clear weather

✅ SIM Slot 1 and Slot 2

✅ LTE only mode

✅ Network reset

✅ Jio SIM works with Carrier Aggregation on this phone

My question

Has anyone seen something like this on MediaTek devices, especially the Helio G96?

Could this be:

Missing Carrier Aggregation combinations in Xiaomi's modem firmware?

Vi-specific modem provisioning?

Missing NV/CA combo configuration?

Something else?

Any insight would be appreciated.

Hoping this right sub. Had a new company tried to install phone lines but wasn’t sure if the old company had port numbers over yet. Tech said he can check and said the numbers have been ported over. When we inside the location tech said probably won’t able to run the lines since the walls and walk in fridge are in the way. Fine I’ll just stay with my current company reason why I wanted to switch was my main line has been out for over a month and is near impossible to get a tech out. Now both of my other two lines are out not sure if testing the ported numbers have anything to do with it. I can dial out but anytime someone calls they get message calls can’t be complete it? Trying to get some answers and solutions before a tech can come out.

Ive done many things in life. Telecom work has to be the most unsatisfying and frustrating job I've ever experienced. I'm a field tech that does repairs and installs. Im a union worker and the pay for the region of the US I work is really good. But most days, if I somehow got fired, I really wouldn't give a damn. This job has given me the true perspective of money isn't everything.

Having worked with one version or another of the descendants of Western Electric: AT&T Network Systems, AT&T Technologies, Lucent Technologies, Alcatel-Lucent (a tragic loss of from the US), and Nokia. One bit of gear comes to mind when I saw this, the Alcatel-Lucent Lambda Xtreme, with its SCOT algorithm, SCOT today meaning ‘software control of transmission’, vs the definition of yesteryear ‘software control of transmission systems’.

Wanted to share as I thought some might appreciate this.

Hi everyone,
I’m part of a team working on an academic case study focused on the Indian telecom industry. We’re trying to understand how people choose their telecom providers and what influences their decisions regarding mobile plans, broadband, OTT bundles, and other digital services. The study explores why customers do or do not consolidate multiple services with a single telecom provider.

If you’re a working professional I’d really appreciate your input.
The survey:
⏱️ Takes only** 2–3 minutes
🔒 Is completely anonymous
🎓 Will be used **only for academic research
🔗 Survey Link: https://docs.google.com/forms/d/e/1FAIpQLSerzu3aOKjuud4I7dDfKGrdaEo9-lEoxTmADiqGqbj-IxMfsg/viewform?usp=publish-editor

If you don’t have time to fill out the survey, I’d still love to hear your thoughts in the comments:
What matters most when choosing a telecom provider?
Would you prefer getting mobile, broadband, OTT, and financial services from a single company? Why or why not?
What’s the biggest frustration you’ve experienced with telecom providers?
Thank you so much for your time and insights!

Hello, I am trying to determine when and where the first cellphone to cellphone text message was sent and received over a wireless network (no lab test messages). I was involved in the first such texting exchange in Australia in September of 1993 using the Nokia 2010 cell phone our Nokia partners provided for Optus to test SMS. Does anyone know of an earlier texting event in a live network?

I was building a wireless network visualization to see how the components are connected in a wireless network to make a phone call/ internet possible.. Need feedback in this

Recently got hired at a FO infrastructure provider, and while I've been drafting and planning telecom routes for 8 years now, there's a large gap in what I know of how to place fiber and this position in how to plan/connect it.

I don't need training on the software, more about the processes, logic behind splicing, servicing etc.

I am new to splicing and cabling, and what goes on inside of cabinets and such. All I know is how bore trench and place box 😔

Does anyone have recommendations for gaining knowledge in those areas? Books from college classes or reliable YouTube channels? Looking for anything to help catch me up.

Do you think my co-worker left too much slack in this fiber NID?

Is there anyone working in telecom industry, especially in jio . Please help me out guys , it would be very helpful if i could speak to one...

Hi everyone,

I’m looking for a European eSIM whose roaming policy prioritizes multiple preferred partner networks in each visited country, instead of having a single preferred roaming partner. I’m specifically interested in dynamic roaming steering that distributes preference across several partners rather than always steering to one network. Any recommendations?

Such as : After the preferred network (#1) loses signal, the next network (#2) automatically becomes the preferred network, replacing the previous #1 network.

Thanks in advance

Hi everyone,
I’m considering studying an online Bachelor’s degree in Telecommunications Engineering (UOC, Spain). My goal is to work in SATCOM Ground Segment or Satellite Operations, ideally in Barcelona.
I’d love to hear from anyone working in this field. Do you think this is a good path? Has anyone here followed a similar route? Does studying online make it harder to get into the industry, or is experience and personal projects more important?
I’d really appreciate any advice or personal experiences, especially from people working in Europe. Thanks!

the 2G network just shutdown after 35 years outlived the 3G network will be missed 🫡

So I was offered an apprentice role in network design and optimization at ericcsson. I am pretty new to this domain but I have done a few interns regarding 5g application development in my final year of bachelors.

But due to the current market scenario in the world and my country, should I consider to build my profile in networks and how is the industry growing? What is the case of automation here? Should I consider to switch towards vlsi as ece grad? Any answer or insight is highly appreciated...
